SPECIFICATION forming part'of Letters Patent No. 293,498?, dated February 12,1884.

Application filed June 4, 1883. (No model.)r

To' all whom, it may concern.-

Be it known that I, JOSEPH B. NEFF, a citizen of the United States of America, residing at Burlington, Des Moines county, Iowa, have invented a new and useful Improvement in Wheels for Plows and Agricultural Implements, of which the following is a specification. y

Figure l is a perspective viewoi` my improved metal wheel. Fig. 2 is a sectional view in detail, of parts of my wheel. Figs. 8;

4, 5,and 6 are different views of thehub. Fig.

7 is a sectional view of the rim.

The object of this invention is to improve metal wheels which are especially designed for sulky-plows and other agricultural Wheel implements, which ,are necessarily subjected to very tough usage in moving over rough plowed land.

The nature of `my invention consists in a wheel which is made entirely of metal, the

hub, spokes, and rim of which are constructed and so united that while the wheel possesses great strength it is very light and durable, as will. be understood from the following descripf tion, when taken in connection with the anneXed drawings.

The hub A is made of one piece, having an- V nular thickened portions or belts a a, near ular distances apart.

its ends, and radial nipples b arranged at reg- These nipples `are provided withfemale screw-threads adapted to receive the male screw-threaded inner ends of the spokes. The spokes B are of metal, and their inner ends are screwed into the hub.

`'Iheir outer ends are reduced, so as to form shoulders b, `and the reduced portions are fitted into holes made through vthe rim C of thewheel andriveted in the said rim.

It will be observed that the shape of the` rim, when taken in cross-section, is that of a i double ogeethat is to say, the rim is considerably thickened at the middle of its width at c, and thin at its edges. This gives asuffr cient body of metal to firmly hold the outer ends of the spokes, and allow them to be riveted. 4 -At the same time I have a rim which is very strong and light. It will be seen that I have a comparatively long hub, and thatthe spokes incline toward the `rim C; or, in other words, the wheel has staggered7 spokes,

which serveas lateral braces in two directions,

to prevent the wheel from being dished when subjected to undue side strain.

The manner of putting the `several parts of the wheel together is as follows: The spokes B are provided with j anrnuts e, which are applied on their screw-threaded ends.v These ends are then screwed into the `hub until the rim C will pass around the tenoned ends of the spokes. The latter are then turned back- Wardiuntil the shoulders of the tenoned ends abut forcibly against the rim. The jam-nuts c are then screwed up hard against the ends of the nipples of the hub, after which the outer ends of the spokes are riveted fast to the rim. I am aware that it is not new to make staggered-spoke wheels of metal-the spokes secured into the hub; also, that it is not new to secure metal spokes to metal whee1-hubs by nuts; also, that it is not new to tenon the ends of spokes into the rim of a metal wheel; also, that it is not new to employ angleiron rims for wheels. These features will be found, when annular thickened portions, and re-enforced by nipples b, projecting beyond the diameter of this hub, and having inclined screw-threaded holes through them, the staggered spokes.

Vscrewed into said nipples, the j am-nuts e for the inner ends of the spokes, Vthe rim 0,-centrally "thickened to leave thin edges, and perforated,

and the outer tenoned ends ofthe spokes passed entirely through the rim, shouldered, and riveted to this rim, al1 constructed in the manner shown and described.
